Method of determining effective heat transfer capability of a fluid coolant composition

Abstract

A method of determining effective heat transfer capability of a fluid coolant composition, the method comprising the steps of: determining a critical cooling effectiveness percentage value for the fluid coolant composition; and determining whether the critical cooling effectiveness percentage value is greater than zero percent, thereby determining whether the fluid coolant composition has effective heat transfer capability; wherein the critical cooling effectiveness percentage is high enough to indicate an increased heat transfer capability of the fluid coolant composition and is low enough to substantially prevent deleterious effects on other properties of the fluid coolant composition.

1 . A method of determining effective heat transfer capability of a fluid coolant composition, the method comprising the steps of:
 determining a critical cooling effectiveness percentage value for the fluid coolant composition; and   determining whether the critical cooling effectiveness percentage value is greater than zero percent, thereby determining whether the fluid coolant composition has effective heat transfer capability;   wherein the critical cooling effectiveness percentage is high enough to indicate an increased heat transfer capability of the fluid coolant composition and is low enough to substantially prevent deleterious effects on other properties of the fluid coolant composition.   
     
     
         2 . The method as defined in  claim 1  herein the fluid coolant composition comprises:
 a coolant; and 
 a plurality of nanoparticles dispersed throughout the coolant, the plurality of nanoparticles comprising at least one of metal compounds adapted to react to form insoluble metal compound particles in situ, glass, silica, pumices, and mixtures thereof; 
 wherein the plurality of nanoparticles increases heat capacity of the coolant and enhances heat transfer efficiency of the fluid coolant composition. 
 
     
     
         3 . The method as defined in  claim 2  wherein each of the plurality of nanoparticles has an average diameter ranging between about 1 nm and about 4000 nm. 
     
     
         4 . The method as defined in  claim 2  wherein the metal compounds comprise silver compounds adapted to react with chloride in the coolant to form insoluble silver chloride.
